Hamels (4-1) allowed seven runs on nine hits and two walks while striking out just three batters through 5.1 innings during Thursday's loss to Baltimore.
Hamels also allowed seven runs June 26 in his first start back from a lengthy stint on the disabled list, but had rebounded with a streak of 24 consecutive scoreless innings before surrendering a run to the Orioles in the bottom of the fourth. The flood gates opened soon after that, bloating the veteran's ERA to 3.78 on the season. Hamels' FIP is up to an alarming 4.84 for the year and his 5.0 K/9 isn't moving the needle much either, so things may only get worse for the lefty from here on out.
